cAN-oPENER.

SPECIFICATION forming part of Letters Patent No. 579,084, dated March16, 1897. Application filed August 5, 1896. Serial No. 601,750. (Nomodel.)

To all whom it may concern:

Be it known that I, Roscon BAILEY STEW- ART, a citizen of the UnitedStates, and a resident of Osterdock, in the county of Olayton and Stateof Iowa, have invented certain new and useful Improvements inCan-Openers, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof, in whichsimilar letters of reference indicate corresponding parts. y

This invention relates to can-openers; and the object thereof is toprovide an improved device of this class which is simple in constructionand operation and which is adapted to cut out the head of a can at asingle operation thereof.

The invention is fully disclosed in the-following specification, ofwhich the accompanying drawings form a part, in which- Figure 1 is aside view of my improved canopener; Fig. 2, a plan view of acutting-head which forms a part thereof; Fig. 3, a side view of one ofthe blades connected with the cutting-head, and Fig. 4 a plan Viewthereof, Figs. 3 and 4 being on an enlarged scale.

In the practice of my invention I provide a can-opener which comprises abody portion A, which is provided on its outer side with shoulders orprojections a, through one of which passes a screw B, and by means ofwhich the device may be secured to a table or any suitable support, andthe body portion A is provided at its lower end with an arm D, which ispreferably provided at its outer end with an upwardly-directed tubularshoulder d, and passing through said shoulder and through said arm is ascrew-threaded bolt d2, the upper end of which is provided with a diskor plate d3. Pivotally connected with the upper part of the body portionA and in line with the arm B is a lever G, which is provided withdepending shoulders or projections g, but one of which is shown, andpivotally connected with said shoulders or projections g is a circulardisk or head 92, which is provided with a plurality of blades H, each ofwhich is segmental in cross-section, and each of which is provided atits upper end with a screwthreaded bolt h, which is designed to passthrough aradial slot 93, formed in the head 92.

It will be observed that each of the slots g3 is provided with bladesII, and said blades are preferably of the form shown in Fig. l, a slightmodification of which is shown in Fig. 3, said blades being curveddownwardly and forwardly, and the` rear sides h2 thereof being providedwith cutting edges, and each blade being provided with a point hs, andthe forward sides thereof being slightly curved and provided withcutting edges at ht, and secured to the outer side of each blade is alng or projection K, which is preferably composed of spring metal whichis secured thereto in any desired manner, and by means of Which the headof the can after it is cut out may be removed.

The screw-threaded bolts h on the blades H are provided with nuts h, andit will be observed that the extreme rear portion of the cutting edge h2and 716 overlaps the forward portion 714 of the blade adjacent thereto.It will also be observed that by means of the slots 93 in the head 92all of said blades may be radially adjusted, and thus the device may bemade to accommodate itself to the heads of cans of diiferent sizes, andthe operation will be readily understood from the foregoin g descriptionwhen taken in connection with the accompanying drawings and thefollowing statement thereof.

It will be understood that the device is secured to a table or anypreferred form of support, and whenever it is desired to cut out thehead of a can said can is set on the disk or plate d3 and the lever G isdepressed, so as to force the blades H through the head thereof, and inthis operation the head is entirely cut out, and when the lever Gisiraised the head will be removed by the spring lugs or projections K.

The dotted line or lines at L in Fig. 2 represent the circular positionof the blades, and it will thus be seen that the head of a can maybequickly and easily cut out by a single operation of the device, andinstead of cutting out the entire head the blades H may be so arrangedas to leave anarrow space, as shown at M in Fig. 2, in which event thatportion of the head cut out may be turned backwardly and left inposition, as will be readily understood, and it will be apparent thatchanges in and modifications of the construction described may be madewithout departing from the spirit of niy invention or sacrificing itsadvantages.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- 1. A can-opener,comprising a suitable body portion,Which is adapted` to be secured to a table or other support, and whichis provided at its lower end with an arm -through which passes aVertically-movable bolt or rod, Which is provided at its upper end witha disk or plate, and said body portion being provided at its upper endwith a pivoted lever, with the under side of which is pivotallyconnected a head or disk, to the under side of Which is secured aplurality of cutting-blades Which are arranged in a circle,substantially as shown and described.

2. A can-opener, compris'ng a suitable body portion, which is adapted tobe secured to a table or other support, and which is provided at itslower end with an arin through Which passes a Vertically-movable bolt orrod, which is provided at its upper end with a disk or plate` and saidbody portion being provided at its upper end with a pivoted lever, withthe under side of which is pivotally connected a head or disk, to theunder side of Which is secured a plurality of cutting-blades which arearranged in a circle, and Which are projected forwardly and downwardly,substantially as shown and described.

3. A can-opener comprising a suitable body portion, Which is adapted tobe secured to a table or other support, and which is provided at itslower end with an arin through which passes a vertically-movable bolt orrod, which is provided at its upper end with a disk or plate, said bodyportion being provided at its upper end with a pivoted lever, with theunder side of which is pivotally connected a head or disk, to the underside of which is secured a plurality of cutting-blades which arearranged in a circle, and which are projected forwardly and downwardly,said blades being also radially adjustable, substantially as shown anddescribed.

4. A can-opener comprising a suitable body portion, which is adapted tobe secured to a table or other support, and which is provided at itslower end with an arm through which passes a vertically-movable bolt orrod, which is provided at its upper end with a disk or plate, said bodyportion being provided at its upper end With a pivoted lever, with theunder side of Which is pivotally connected a head or disk, to the underside of Which is secured a plurality of cutting-blades which arearranged in a circle, and 'which are proj ected forwardly anddownwardly, said blades being also radially adjustable and provided withmeans Whereby the head of the can When cut out is removed, substantiallyas shown and described.

5. The herein-described device for opening cans, consisting of asuitable body portion, which is adapted to be secured to a table orother support, and Which is provided at its lower end with avertically-movable plate, Which is adapted to support the can, and atits upper end with a pivoted lever to the lower side of Which is pivoteda head or disk, said head or disk being provided with a plurality ofdoWnwardly-directed cutting-blades, which are arranged in a circle andby Which the head of a can may be cut out at each depression of thelever, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing Witnesses, this 9th day of May,1896.
